Bitwalking

Bitwalking is a digital currency introduced by project founders, Franky Imbesi and Nissan Bahar. Each Bitwalking dollar (BW$) is earned by walking approximately 10,000 steps, or 5 miles (8 km). While each BW$ will be equivalent to $1 in the Bitwalking online store, the real-world conversation rate of each BW$ is not known.

A free mobile application is used to count and convert a user's steps into Bitwalking dollars. The amount of Bitwalking dollars a user can claim per day was capped at 3BW$ at launch. Users can also join its Bitwalking Beta Program to try new features of latest beta version app.
